Be it known that I, HOMER C. LA Barr, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Im rovements in Stop-Re ters for Sheet-Fee ing Machines, of whic the fol:

lowing is a specification.

My invention relates to a front register or stop particularly adapted for use with mechanism for transmitting or delivering sheets of paper to a printing press, folding machine, ruling machine or other machine employing or acting upon sheets of paper, and is designed to square or register the sheets before the latter are taken by the grippers or other 'receiving'mechanism of the associated machine to..which the sheets are delivered.

The invention consists of the combinations, arrangements, and organizations of part-s hereinafter particularly described and then pointed out in the appended claims.

This application is a division of an application filed by me March 8, 1904, Serial No.

"197,083, and in illustrating the construction and arrangement of the invention herein, I have shown the same adapted ,to the sheet feeding machine shown and described in the said application. It is to be understood, however, that the invention is not restricted to any particular type or construction of sheet feeding machine, but may be readily adapted to and employed-with any other or preferred character of mechanism for transmitting or deliverin the sheets to an asso- 'ciated machine emp oying or acting upon sheets of paper.

The feeding machine with which the present invention is shown associated, may be supported in any suitable manner, as for example as illustrated, jand comprises a pair. of side rails C, one of which is illustrated in, Fig. 1, each side rail being carried by a bracket 0 bolted tothe side member a of a sheet separating machine A. The forward end of each of the rails C- is supported by a block 0' carried by a bracket c, fastened to the frame of the associated printing press or other machine to which the sheets received from the sheet separating machine A are delivered by the sheet feeding machine. In the construction illustrated the' side rails C are so disposed that'the forward ends of the same extend under'the rearend .of the I ,feed board or table 6 of the printing press and serve to support an extensible section which comprises a pair of side bars D mov- .85

able through or in' guide apertures formed in blocks or boxes d fixed to the side rails C and alsothrough or in alinedfapertures in the blocks 0. The bars D are tied 'together or connected at their rear orfree ends by across bar d which is bolted at each end .to bracketed, d fixed to the ends of the The feeding machine is provided with suitable means for delivering the sheet to the cylinder b of the printing press or associated machine. In the present instance vover or around the feeding-o such means consist of a series of endless tapes or-'bands'carried by' each section. As. shown in Fig. 1 the endless "t es 0 pass if ro1l (not shown) ofthe sheet feeding machine and a. roller cflwhich is mounted on a; shaft suitably journaled at itsends-in the blocks-0' These ta es 0 maybe spaced apart any suitable istance: and carry the sheets to the tapes 01* of theeiitensible section, the hitmanner as through the medium of suitable tertapes-passing around the rollerc and. at'thelr forward. ends over a roller (1 which is journaled at itsends in the blocks d d The tapes may be driven in any suitable connections from the sheet separating mas chine A, and in operation, the tapes a turn-" ing the roller 0, the tapes (i are driven 'at the same surface speed as the tapes 0 From the foregoing it will be understood that as construction the section. WV on it is desired to feed the sheets .1 0 the press by hand the extensible section of the feeding Etnachine is retractedand the foldable section b of the printing press feed board is folded down into operative relation with the press cylinder.

. .Anysuitable means may be provided for advancing and retracting the extensible sec-. tion of the feedin machine. In the present are D are made in the form of rack bars, with the teeth of each of which meshes a pinionc, fixed upon a cross shaft 0 journaled in bearings 0" depending from the guide boxes or blocks (I, as shown in Fig. 1. A hand wheel 2? is fixed on the i shaft 0, and by turning such hand wheel the bars D may beadvanced or retracted at will, all as more fully shown and described in the application for patent hereinbefore' referred to.

Associated with and carried by the feeding machine at its rear end isa registering device which is designedto register or aline the front or advancing edge of each sheet. This front registerniay be of any suitable construction adapted-to the attainment of the desired ends. In the present embodiment of the invention it consists of a blade F which is. periodically and automatically lowered into the path of the advancing. sheet of paper and is then raised afterthe front ledge ofthe paper has been alined with the gagesof the press. This blade in its operative positionjoccupie's a vertical position in the pathof the paper as clearly shown in Figs. land 7}? and 1s provided at its upper edge with'a flange f, which not only serves to strengthen the blade, but also provides means by which the ends of the blade are bolted to a pairofarms f. These arms are fixed to a rock shaft 7, one end of which is journaled in xan'ear f of the support d, while the other end. is journaledin an extension f of the block (P, as seen in Figs.

1, 2 and 3.. Fixedjtoone end of the shaft f is a crank" arm f" to which is. jointed one end of a link ff, pivoted at the other end to a slide .f", moving in a guide or way formed in the block d as clearlyseen in Figs. 2 and 3. Attached-to the slide f is one end of a connecting ro'd f extending parallel with the side rail 0 and connected at its other end to a'slide-f" mounted and moving in a way formed in the block 0, as shown in Figs. i and 5. Pivoted to the said block 0 is an arm f provided at its up er 'end with a slot f which receives a stu fflprojecting from the slide f The arm f is designed to be actuated by a cam, which may take the form of a disk g, having a radical enlarge- .ment or cam face 9', fixed on a cross shaft 9 journaled at the end in the block or box a. Preferably the arm is provided with an antifriction roller f in the plane of movement of the disk 9' so as to be engaged at the proper time by the cam g to move the connectmg rod f forwardly and through the medium of the connectin mechanism rock the shaft f and lower t e blade into the path of the advancing sheet as, shown in Fig. 7. When the cam 'portionof the disk passes out of engagement with the antifriction roller 7, the blade is raised in any suitable manner, as by'means'of springs f,

which are coiled about the rock shaft f and each of which is anchored at one end to one of the arms f while theotherend is Ittached to the supports for the shaft, as

clearly shown-in F1g.2, so as to normally exerta tendency to elevate the blade F. The shaft 9 may be driven in any preferred manner, as through the medium of a shaft 9 and the intermediate gearin shown in dotted lines Fig. 5, andthe shaft has motion communicated to it through the me-' dium of bevel gear g fixed. thereto and which derives motion from the associated machine,' s uch as the printing press orother source. Itfistobe understood, however,

that the arrangement of the connections for driving the various operative parts of the machine is not material and may be varied as desired.

.In order to adjust'the blade F to the line of the front edge of the sheets, in the event that such edge should not be cut at an exact right angle 'tothe sides of the sheet, the.

arms f may be provided with elongated slots f as shown in 7 through which the securing bolts therefor pass. By this arrangement either end of theblade may be moved to adjust the blade to any desired angle.

The sheets of paper pass from the rear.

end of the tapes a? tea delivery device which in the present instance consists pf fingers It, which, when the extensible sectlon is inits' operative position, occupy the posit-ion and take the place of the deliveryfiiige'rson the hinged section of the press hand feed board.

Each of the fingers h' mounted upon a bracket; 71., carried'by the cross bar d, and adjustably secured thereto by means of a, set screw k as seen in Fig. 7\- The blade F of the front gage when in active position stands in advance of the ends of the fingers it in the path of the moving sheets solthat the sheets'passing, over the fingers willnecessarily engage the blade. In order to prevent the sheets of paper from passing the ends of the fingers h and slipping under the blade, the fingers are provided with spring extensions [L3 fixed to the said fingers and projecting in advance of the latter in such position that the blade F rests thereonwhen in its depressed position, thereby rendering it impossible for a sheet to slip on the fingers and under the blade and the springextensions. Two of the'spring extensions h are extended sufficiently to project over thepresscylinder so as to coact with the press ages which in their depressed position rest =1pon said extensions as' shownin Fig. 7.

It is obvious that instead of the fingers h the delivery device may be in the form ofa plate extending substantially the width of the machine.

A suitable side register device, adapted to register the side edges of the sheets of paper to place'the same in predetermined position for proper alinement with'the 00- operating part ofthe associated printing press or other machine, maybe employed if desired, and such register may}. be of the character shown and described in the application hereinbefore referred to or of any other preferred type. Two such side registers S QS, located at opposite sides ofthe feedingmachine, are indicated, although only one of such resistering devices is in operation at a time, the other. being adapted to register the same sheets when reversed afterbelng printed on one surface to 1nsure uniformity of impresslon-on opposite surfaces of the sheets. These side registers in the embodiment of the invention illustrated are designed to register the sheets after they have'been acted upon by the front stop or register. The stop plate F in its inoperative position occupies a raised posi'-- tion, as shownin d6tfdl1nes in Fig. 3, and

w as a sheet advancesthe plate is lowered into its pathto square the front edge of the same. The platei'sftlien e fiva ted out of the way of a the sheet by the springsf, as the camportion g .moves out of engagement with the arm 7", and the sheet is then carried by the tapes to the pres's gages, which rest at their ends on" the spring extensions 'h of the delivering deviceand arrest'and'gage the sheet in the usual manner as when the press is by hand. During the periodthat the sheet is'h'eld by "thelpress gages it is registered by the activeside register device, and

the press gages being then moved out of the the sheet. is'taken by the grippers of the press in the usual manner.

In order to permit the advance and re traction of'the' extensible section of the feeding machine, the connecting rod i instead of being permanently fixed to the slide 1 eXtendsthrough-an apertured lug or ear'f on the said shde and is provided at its end with a shoulder such as the nut f" and at a suitable oint at the. opposite end of the slide wit a nut j which screws upon a threaded'portion f" of the red as shown in 4 and 15, thereby detachably connecting the rod to the slide. When it is desired to move the extensible section rearwardly the nut f is unscrewed, permitting the rod p to slide through the apertured' lug f on the slide.

Carried by suitable brackets or rods 4',

which may be bolted at'suitable intervalsalong and transversely to the sections of the frame of the machine, are guides located just over the plane of the tapes 0 and d to-hold i the sheets carried bythe tapes against the latter and to prevent the sheets from buckling or curling .up at the edges. These guides consist ofstraight rods or wires 2' and are designed to be adjusted vertically and laterally in order to coeperate with paper of varying thickness, flexibility and fix the blocks in any desired position but permit of the blocks being moved along the rods to adjust the guides-laterally. The guides r may be attached to the arms 0* in any suitable manner. In the present instance Ihave showneach of the arms provided Witha section 1" between which and the arms r the wires are clamped by thumb nuts 1 Any number of the guides. desired may and set screws 1* passing through the ears rectly over t be employed and they may be located dithe bar, delivery fingers fixed to the brackets h and certain of which .are provided with e tapes or intermediate of the tapes. When the extensible section is to be advanced or: retracted in thelmanner heretofore described the nuts 7- are loosened so that the" guides will slide freely in their' supporting arms.

The rear ends of the guides-'1" of the extensib'le section preferably extend over the delivery device of the feeder, as shown in Fig. 7. These guides cooperate with the delivery device and forma narrow throat terminating adjacent the plate F and prevent any buckling or curling of the sheets by their impact on the gage.- Having. described my invention what- I claim as new and desire to secure by 'Letters Patent is p ,1.
